Your questions answered on artificial intelligence

You submitted your questions about artificial intelligence and robotics, and we put them – and some of our own – to The Conversation's experts. It is 100% plausible that we'll have human-like artificial intelligence. I say this even though the human brain is the most complex system in the universe that we know of. But there are also no physical laws we know of that would prevent us reproducing or exceeding its capabilities. Popular AI from Issac Asimov to Steven Spielberg is plausible. What the question doesn't address is: when will it be plausible? Most AI researchers (including me) see little or no evidence of it coming anytime soon. Progress on the major AI challenges is slow, if real.
